PROBLEM TO BE SOLVED: To reduce the occurrence of image defects due to deviation of print image types while maintaining high-speed and high-quality images stably at high speed for a long time in a tandem full-color image forming apparatus To provide a set, an electrostatic latent image developer using the same, and an image forming method. SOLUTION: A set of color toners, wherein an external additive is added to the surface of each color toner, and the external additive contains silica and titania, and the addition of silica and titania in the black toner. When the amounts are SiB and TiB, respectively, and the addition amounts of silica and titania in the other color toners are SiC and TiC, respectively, these are color toner sets that satisfy the relationship of the following formulas (1) and (2). 0.6 <SiB / SiC <0.9 Formula (1) 1.1 <TiB / TiC <1.4 Formula (2) [Selection figure] None |
